StatementDB vacuum support #130

Closed vyzo closed 7 years ago

vyzo commented 7 years ago

Adds support for vacuuming the StatementDB:

Incremental vacuum can recover space following deletes.
Full vacuum recovers space and compacts the database. However, it needs lots of free space (as much as the live data set).

Implementation:

New node databases are now created with auto_vacuum=incremental
/vacuum/incremental performs an incremental vacuum, if it is enabled in the db.
/vacuum/full performs a full compacting vacuum, and it also sets the auto_vacuum mode to incremental for migrating existing node databases.
